You may want to try the diagnostics.
If power is good at the terminal strip, unplug the unit.
Check the heater with a meter, it should be about 13 ohms.
Check the hi limit thermostat, it should be o ohms.
Check the control thermistor, it should be about 50,000 ohms. At least that is what is shows in the wiring diagram. With this part it is a good idea to disconnect at least one side of it when measuring it so that you do not read an alternate/parallel circuit path.
